Clinton was asked by CNN's Erin Burnett about Trump's claims that Hillary Rodham Clinton, the front-runner for the Democratic presidential nomination, was "perhaps the worst secretary of state in history."
The former president responded by praising his wife's work on Iran, nuclear proliferation and AIDS prevention and said that if Trump wins the Republican presidential nomination, "he'll have to sort of hone his criticisms a little more finely because the facts will be easy to marshal."
Clinton said he thought Trump and some of the other Republican candidates "believe that authenticity is created by making your campaign look as much like a reality TV show as possible."
Clinton was also asked about the ongoing investigations into Hillary Clinton's email use during her time in the Obama administration. "That'll play out however it does," he responded. "But she's the only secretary of state in history that ever said, 'Just release them all, all my work-related emails.' And so far, as I said, you get the record out, I think she looks great."
